To all whom it may cof/wem: f l

Be it known that I, WILLIAM EMERGER, subject of the Emperor of Germany, residing at Niles, in the county of Berrien and State of Michigan, have invented certain new and useful Improvements in Draw-Bar and raft Attachments," of which the fol` lowing is a specification.

This invention relates to draft gear for railway cars and is designed to prevent the pulling out of the draw bar and the casualties attributable to this cause.

he invention also aims to simplify the attaching means employed for connecting the draw bar to the car body and to obviate the use of the ordinary yoke and rivets.

While the invention may be adapted to different forms and conditions by changes in the structure and minordetails without departin from the spirit or essential. features thereo still the preferred embodiment of the invention is shown in the accompanying drawings.

For a full understandin of the invention i? also to a uire a knowledge of the details of construction of the means for effecting the result, reference is to be had to the following description and accompanying drawings, in which: c

Figure 1 is a side view of a'draft attachment embodying the invention, showing end portionsof vadjacent; cars in section. Fi 2 is a top plan view of the parts illustrate in 1. Fig. 3 is a transverse sectionuonthe line 3 3 o Fi 2, looking in the direction of the arrow. Fi 4 is a transverse section on the line 4 4 o Fig. 2 looking in the direction of the arro Fig. 5 is a perspective view of one of the draft timbers. Flg. 6 is a perspective view of the draw bar, the coupling head being broken away.

Corresponding and like parts are referred description and indicated to in the followlng 1n all the views o the d'rawings by the same `reference characters.I

The draft ear comprises a draw bar 1 and draft tim ers 2 the latter havin a parallel arrangement and being secured to the bottom r platform of the car body in any substantial way. The draw bar 1 may be outer end with a-coupling head 3 of any type or variety. Lugs 4 project from op oslte sides of the draw ba-r and are provide in front andrear pairs. Slots 5 are formed inthe draw bar and their end e portions of the. ross'bars p 15 areformed-fin the'cap lplaces 12 Y portions extend through the sides of the lugs 4 which face iwardporftoward each other.` The vslots 5 are elongated lengthwise of the draw bar to provide for a limited longitudinal movement of the latter. Recesses 6 are formed in the inner-wallsof the draft timbers 2 to receive'pthe lugsv y4,' said recesses being ofa'length to admitof the draw bar having a limited longitudinal movement. The upper endsof the Lrecesses `6 are closed, whereas their lower ends .are open. By having 'the upper ends of the recesses 6 closed the draw bar is preventedV from upward movement and crowdin ainst the lower side of the bottom or p atorm of the car. Slots 7 are formed in the draft timbers' and communicate with the recesses Gand extend lengthwise'of the draft timbers to admit of the draw bar moving longitudinally.

Cross bars 8 slots 5 and 7 of their end portions projectin outer sides of' the draft tim cross bars 8 are prevented from having any appreciable vertical play in the slots 5 and 7 but have a limited play in the direction of the length of .said slots'v or longitudinally of the draw bar and draft timbers. Stout springs 9 are interposed between the projecting ends of the cross bars 8 and sustain the load both in pulling and pushing.

In order that the cross bars 8 may be of a length and better -adapted to sustain the strain, the outer sides of the draft timbers 2 are recessed, asyindicated at 10, saidrecesses forming seats to receive a proximately one-half of the springs 9. `Ro s or bars 11 support the springs 9 and are mounted at their ends in the projecting end portions of the cross bars 8. Cap-pieces 12 are mounted upon opposite end ortions of the rods or bars 1l and receivet e ends of the springs 9. The' inner ends of the cap-1' pieces 12 are recessed to receive the ends of the springs 9 which are seated therein and projections 13 extend from'the inner ends of the cap-pieces and ass into' the'ends of the springs 9 a short distance `and serve to centra'lizeA said springs and-retain them in proper position. The outer ends of the cap pieces 12 are reduced and openings. 14 are ormed therein to receive the 'projecting end Longitudinal pass transversely through the and are lof la length to admit beyond the rs 2.- The` openings andreceive the rods or bars 11, e hitter terially in support which it passes;

passing through openings 16 in the end portions of the cross bars 8. Pins or-keys 17 pass throughslots formed in the ends 'of the rods or bars 11 and serve in conjunction with the heads of said parts 11 to hold the latter in place. Draft 'chains 18 are connected with the rods or bars 11 and may extend bef tween the ends `of adjacent cars to assist masustaining the draft in the event of the usual coupling means becoming disarranged or incapacitated for the purpose designed. Y.

A bar 19 is supported in the forward ends of the draft timbers the front portion of the draw bar 1 to sup port lthe latter. This bar 19 is suiciently stout to resist the usage to which it is subjected when in service. The crossl bars 8 the rear portion of the draw bar and under normal conditions sustainv the load both in pulling and pushing. When pushing inward upon the outer end of the draw bar the rear cr'oss bar S engages with the rear ends of the slots 7 through which it passes, and the front cross bar 8 engages with the front end of the slot 5 through hence the front cross bar moves rearwardly Withthe draw bar thereby compressing the springs 9.` IVhen pulling upon the draw bar the front cross bar 8 en-` gages with bar 8 engages with the rear end lof the slot 5 through -Which it extends. As the draw bar 1 moves forward the rear cross bar S likewise moves forward with it and compresses the spring 9, which sustains the pulltion'of draft tlmbers havin `recesses,

2 and extends beneath` the front ends of the slots 7 through which it passes and the rear cross size as to admit 'of the draw bar having a limited longitudinal play'.

2. In draft ear for railways kthe combinaa'draw bar arranged betweenthe raft timbers and having lugs extendin the draft timbers an having limited play therein to` admit of a longitudinal movement of the draw bar, cross bars extendin transversely through the draw bar, an draft timbers, and khaving their opposite ends projected beyond the adjacent sides of thedraft timbers and springs interposed between the cross bars to normally sustain both the pulling and pushing force.'

The combination with a draw bar and draft timbers having cross bars extending transversely through the same, cap pieceshaving their inner ends recessed and formed into Athe recesses ofy Vith centrally disposed projections and havformed the ends of the cross ing their outer ends reduced and with openings to receive bars, said cap pieces openings; rods mounted in the openings of the cap .pieces and cross bars and springs and cross bars having coiled around said rods and nested within the cap pieces.

4. In combination, upon their inner. sides with recesses and having their outer sides recessed to form seat-s said draft timbers having longitudinal draft timbers formed i lslots in communication withthe recesses, a

draw bar lmounted betweenthe draft timbe'rs and having pairs of lugs extended into the recesses of the draft timbers, said draw bar having longitudinal slots extended through the inner sides' of said lugs, cross bars passed through the slots of the draw bar'and draft timbers and having their ends extended beyond the outer sides of the draft timbers, capepieces secured to the projecting ends 'of the cross bars, and springs interposed between the cap-pieces. v

In testimony whereof I aiix my signature in presence' of two witnesses.
